Working principle of needle printers

The printer itself is a micro-computer system, and the work of the whole machine is controlled by the CPU. Its control program is stored in ROM, so that the CPU can start to work. The CPU can receive all kinds of control instructions from the panel or from the host, and interpret and execute all kinds of instructions. These connections are made through computer interfaces. There are two working modes of needle punching: Text Mode and Bit Image Print Mode.

Text style

Printed data of needle printer is obtained from host computer through interface with computer. The printer’s printed data is the ASCII codes of the characters to be printed, which are stored in the print buffer of the printer. The printer sends a BUSY (busy) signal to the host after each time the data transmitted by the host is filled with the print buffer. When the host receives the signal, it pauses sending data, and then the printer starts printing.

After printing begins, the CPU in the printer takes out the ASCII code of the printed character from the print buffer, and calculates the first address of the character lattice storage area corresponding to the character. Take out the dot matrix code of each column one by one according to the address, drive the printing needle, hit the ribbon, and form the printing characters on the printing paper. There are 96 ASCII codes and some special character font codes in the printer’s character generator ROM (some printers also have dot matrix codes of Chinese characters, such as LQ-1600K). When the data printing in the buffer is completed, the printer is opened again to receive the new printed data from the host and start the new printing process.

If you need to print graphics or Chinese characters (for printers without Chinese character library), the host can send out the pixel signal of graphics or Chinese character font code. Obviously, this printing method is similar to that of displaying characters on the display.

Bit mapping

In this way, the print data sent by the computer is the data that controls the pin-out and pin-closing of the printing needle, so the programmer can directly write a program to control each pin and print out the graphics, tables and Chinese characters.

What are the precautions when buying toner cartridges?

When buying selenium drums, it’s better to buy brand goods. After all, in the area of office products, manufacturers still attach great importance to their brand image. Suggestions that you can go to brand stores or to ensure that the manufacturer’s direct sales of the Colip Mall selection, are quite good choices. It can be said that the process of buying toner cartridges is actually the process of distinguishing genuine and fake toner cartridges. The poor quality of selenium drum charcoal powder usually results in poor printing quality. It is easy to overlap the ink deposited inside the printer, which has a negative impact on the photosensitive drum and printer.

In addition to the appearance of “observation” to identify true and false selenium drums, but also through the most direct printing effect to distinguish true and false selenium drums, when it is best to take the original drum output sample for effect comparison. The printing effect of true and false selenium drums is far from each other. When put together, there will be a sharp contrast. Under normal working conditions, the text lines printed by the original drum are very clear. If it is color playing, the color restoring ability is good, and the image is full and bright. In the printing of counterfeit products, line breakage, inadequate color restoration ability and word breakage occur when printing a large number of words.

How to identify the quality of toner cartridge before use it?

It is difficult to distinguish true from false. Here’s a detailed introduction to you: how to pick up the toner cartridge? 1, first of all, we should carefully observe its outer packing. You will find that the outer packaging of the original selenium drum is usually printed beautifully, brightly colored, and the serial number on the back is printed with special technology. When you look carefully, the background of the serial number will have a rectangular offset frame, while the serial number of the counterfeit product has no trace of such offset printing, and the counterfeit product is usually gray and printed. Blurred image and rough quality, there is a big gap between genuine and external packaging printing.

Then take a look on the inner packing of the toner cartridge. Generally, the inner packing of the toner cartridge is black or silver electrostatic packaging bag. Choose not to re seal, seal or seal the size of the two sides of the phenomenon. The electrostatic packaging bags of counterfeit selenium drums are thin and crisp. The whole packaging surface is not smooth and smooth enough. Some of them have rubbed or unclean marks. Many counterfeit products have problems of sealing and re-sealing at the seals.

Do you know how to choose the paper for printing?

Self-adhesive paper comes from Japan, and compared with sulfuric acid paper, it is matte and thinner. It is easy to stick with adhesive tape. However, the printing effect of inkjet printers is very unsatisfactory, there will be very obvious ink beads, saturation is very low, it takes a long time to dry, and use the hand will rub ink. However, the above problems do not exist when using laser printers, and vice versa.

Choose direct seal consumption, or print black and white, high-quality patterns, such as digital English.

Summary: It is recommended that inkjet printers do not use self-adhesive paper, laser printers are very recommended to use self-adhesive paper printing.

Self-adhesive art paper, simply speaking, is a common printing paper with backing glue, which can be written, because it is easy to paste with backing glue. The saturation is very high. It is very suitable for printing details. It’s a piece of paper that I personally like very much. I will print it with photos.

Conclusion: high saturation can be used in writing.

Kraft paper self-adhesive pape, divided into two kinds of deep leather and shallow leather, color and touch are not the same. Similar to Muji, the bags are light hide and smooth paper. Deep leather has a rough touch and I don’t know how to use it.

Conclusion: I usually use shallow calf self-adhesive pape.

Our Leader Asked Me to Buy a Toner Cartridge…

When I first joined the company, I was just an ordinary printer.

One day, the toner cartridge of the office printer are ran out. Our leader asked me to buy a set of toner cartridge online. Our company used the color LaserJet Pro MFP M274n printer. I noticed that the corresponding model was HP 131A toner set. I saw the original one demand of $315 in Amazon and I did not hesitate to buy it after reading and evaluating it.

After receiving the product to our leader, our leader immediately got mad.

He took out his mobile phone and opened the V4ink website to tell me that it was not easy for a startup company to operate. Why did I spend money in a random way? Don’t I know that buying compatible toner cartridges can save a lot of money? I took a look at the mobile phone, V4ink 131A combo pack 4 pack only cost $56.99, I was shocked, how can it be so cheap, compatible toner cartridge price is only 1/5 of the original one. After being criticized by my boss, I decided to have a good understanding of the toner cartridge industry.

The present situation of toner cartridge:

At present, there are three main types of toner cartridge in printer toner cartridge market, which are original OEM toner cartridge, compatible toner cartridge and remanufactured toner cartridge.

The difference of this three types of toner cartridge:

Original toner cartridge: the best quality, the most expensive price, good after-sales service.

Compatible toner cartridge: Manufactured by a third-party manufacturer, the price is affordable, but the quality and service are uneven.

Remanufacturing toner cartridge: Re-filling toner by recycling used toner cartridge to make it reusable, the lowest price, but the worst quality, easy to leak powder phenomenon.

Generally speaking, compatible toner cartridge is most suitable for start-up companies, especially for high-quality compatible toner cartridge. The printing effect is almost comparable to that of original toner cartridge. If you want high quality, you should choose the original toner cartridge. In addition, it is better not to use the remanufactured toner cartridge, because it is not only prone to powder leakage, but also damages your printer equipment, later maintenance costs are higher, not worth the loss.

How to Solve the Problem of Toner Cartridge is Expensive and Used Quickly

A friend of mine started a business, a small startup company with only 10 people. They bought a color printer LaserJet Pro 400 color Printer M451dn. And ten toner cartridges at a time, usually for two months. On Black Friday and national holidays, sales doubled, and the amount of toner cartridge printing doubled or more. Over the past year, at least dozens of toner cartridges have been used. The annual cost of a toner cartridge is far more than that of a printer.

Printing can’t be less, but there are cheap ways.

Until last year, he came to me and asked me how to save money on the toner cartridges, because it was very difficult to run and maintain a startup, hoping to save some money on the toner cartridges.
I did not hesitate to recommend V4ink to him, and told him that the quality of many compatible toner cartridge brands is very good, completely comparable to the original product, but the price is only 1/3 of the original product price. My friend can’t believe how much money he’s been wasting.

What printers are suitable for small print shops

For a print shop, buying a multi-functional printer is more cost-effective than buying multiple single-function devices. If you are planning to open a small print shop, I would like to give you some advice:

1. It’s better to choose multifunctional printer

A multifunctional printer is often much cheaper than buying a copy machine, a scanner and a printer alone, and it saves you more space.

Multifunctional printers are not expensive at present. Prices range from $500 – $2000, depending on the printer’s function, printing speed, brand and so on. In addition, to open a printing shop, you should choose a color printer, instead of a black and white printer.

Generally speaking, inkjet printers print color photos better, but the printing speed is slower, while laser printers are suitable for printing general documents, and the color reductivity is slightly worse than inkjet printers. But laser printers are fast. If your print shop is located near the school, laser printers are more suitable.

2. Choose a ink or toner cartridge that are easy to find

Find a ink or toner cartridge easy to find and low cost. Because ink and toner cartridges are the most expensive part of printers. If you buy a new printer, only the original toner cartridges can be selected, and you will find that the new ink or toner cartridges are generally expensive and difficult to find. I suggest you buy a printer, which is mature and having more choose with compatible ink or toner cartridge, it will save you more money.

3. In addition, you should consider some additional conditions

For example, it is better for a printer to print on both sides than on one side. It is better for a printer to print multiple sizes of paper than to print only one size of paper.

In conclusion, I recommend HP M476 series printer. Although the printer is expensive, it is a set of Print, fax, scan, copy printer. In addition, if you buy compatible HP 312X toner cartridges in V4ink, only $17.99 for black and $49.99 for full 4 color set. It is a cost-effective printing device. It will save you a lot of money in the long run.
